I have to come up with an investigation to determine the rate of transpiration in plants..the experiment has to be done at home..any suggestions for apparatus ..method ..and any help with the results would be nice ..please help
Available on the market are eye protectors with transparent side shields. I use them when I am sharpening drill bits on my wheel grinder. They are very effective eye shields.
Most dry chemicals put out the fire by blanketing the area and creating a physical barrier between the fuel and the oxygen. (Fires need fuel, heat, and oxygen to start the chemical reaction we call fire.) Class A dry chemical, also known as ABC chemical and multipurpose dry chemical, is usually comprised of monoamounium phosphate. The class A chemical, although mildly corrosive, will actually adhere to the burning surfaces of fuel, such as a tire fire or a pile of trash. Class B chemicals, usually, sodium bicarbonate (also known as baking soda) will blanket a flammable liquid or grease fire nicely, but doesn't work so hot on class A materials, thus it doesn't receive a class A rating. There are other dry chemical and dry powder agents. Purple K, Class D Met-L-X, and a few other class A variants.

They remove oxygen or block access to oxygen. Fire needs oxygen.
